Velocity Review

Isaac- Graham

What is velocity

Velocity measures how fast something is moving plus the direction that the object is moving. So a car driving from Baltimore, Maryland, to Norfolk, Virginia, might have a velocity of 70 miles per hour south.

Velocity

Speed is how fast something moves.

Velocity is speed with a direction.

Saying Ariel the Dog runs at 9 km/h (kilometers per hour) is a speed.

But saying he runs 9 km/h Westwards is a velocity.

Multiple Choice

Velocity is both ____ and _____.

speed , direction

direction, mass

volume, density

direction, magnitude

a car runs out of gas and slowly rolls to a stop

a car decreases speed at a constant rate until it comes to rest

car has constant speed and is traveling on a straight path

the car travels round trip and is back at the starting point

Multiple Choice

speed up

slow down

make turns

All of the above

Multiple Choice

Acceleration is defined as the CHANGE in

time it takes for one place to move to another place.

velocity of an object.

distance divided by the time interval

velocity divided by the time interval

Multiple Choice

A roller coasters accelerates from an initial velocity of of 6.0 m/s to a final velocity of 70 m/s over 4 seconds. What's the acceleration?
